Dans les solutions techniques de la présente invention, le dispositif de réseau obtient l'adresse IP (protocole Internet) du dispositif de réseau en envoyant un message de requête de route à un routeur publicitaire, obtient l'adresse IP du système de gestion réseau (NMS) en expédiant une requête DHCP (protocole de configuration d'hôte dynamique) à un serveur DHCP, génère une route statique selon l'adresse IP du dispositif de réseau, l'adresse IP du système de gestion réseau et l'adresse IP du routeur publicitaire, et s'enregistre auprès du système de gestion réseau selon la route statique générée. Grâce au procédé mentionné ci-dessus, le dispositif de réseau met en œuvre la découverte automatique entre un gestionnaire de réseau et un dispositif IP qui a rejoint récemment le réseau IPv6, la charge imposée aux opérateurs pour configurer le dispositif de gestion réseau et le dispositif de réseau est simplifiée, et l'efficacité du déploiement de réseau est améliorée.
